INITIAL START-UP OR START-UP AFTER

AUTOMATIC SHUT-OFF

Sequence of Operation

Bin thermostat and the optional drain pump safety

switch must be closed before the ice machine will

start.

1. Initial Start-up or Start-up After Automatic

Shut-off – Water Fill

Before the compressor starts, the water pump, water

inlet valve and hot gas valve are energized for about 3

minutes.

2. Refrigeration System Start-up

The compressor starts after the water fill, and remains

on throughout the Freeze and Harvest cycles. The hot

gas valve remains on for 5 seconds during initial

compressor start-up and then shuts off.

At the same time the compressor starts, the

condenser fan motor (air-cooled models) is supplied

with power. The condenser fan motor will remain

energized during the entire freeze cycle.

3. Freeze

The water pump sprays water into the inverted cups.

The water freezes layer by layer, until an ice cube

forms in each cup. The control system monitors the

temperature of the refrigeration system liquid line to

determine the length of the freeze cycle.
